Let atmega8 define IO pins like Freescale xs128

       Well, I have to admit that I am very used to using Freescale's XS128 microcontroller. But when I first started using atmega8, what I disliked the most was that atmega8 could not operate the IO pins, and had to use some cumbersome bit operations. I don't want to do that. I want to operate like Freescale...

then......

Put the following header file I wrote into include/avr in the winavr directory, and include this header file at the end of the io.h header file.

Hehe, everything has become so intimate and familiar. . . . .
